of New Zealand. It is the easternmost lake in a chain of three lakes to the northeast of Lake Rotorua in New Zealand's North Island. The others are Lake Rotoiti and Lake Rotoehu. Lake Rotoma formed within the Rotoma caldera after lava flows blocked its outlet 10,000 years ago. It is located exactly half-way between the city of Rotorua and town of Whakatane. The lake covers an area of 11.8 square kilometres. Lake Okataina Lake Okataina is the largest of four smaller lakes lying between Lake Rotorua and Lake Tarawera in the Bay of Plenty region of New Zealand's North Island. The others are Lake Rotokakahi (Green Lake), Lake Tikitapu (Blue Lake), and Lake Okareka. Unlike many other lakes in the region, Lake Okataina is completely encircled by native forest. It also has no inlets or outlets. Over the past 30 years, the level of the lake has risen about 5 metres. The lake covers an area of 10.8 square kilometres. Lake Rotoehu Lake Rotoehu is the smallest lake in a chain of three lakes near Lake Rotorua in New Zealand's North Island. It is located between the city of Rotorua and town of Whakatane. It is fed by Lake Rotoma to the east, and flows westward joining Lake Rotoiti. The lake is one of the least visited, but offers great Kayaking and fishing (rainbow trout). The lake covers an area of 8.1 square kilometres. Lake Rotomahana Lake Rotomahana is a small lake in northern New Zealand, located 25 kilometres to the east of Rotorua. It is immediately southwest of the volcano Mount Tarawera, and its geography was substantially altered by a major eruption in 1886. The lake covers a surface area of 8.0 square kilometres. Pink and White Terraces The Pink and White Terraces were a natural wonder located on the shores of the lake. They were considered to be the eighth wonder of the natural world and were New Zealand's most famous tourist attraction during the mid 19th century. They were considered lost in the Mount Tarawera eruption on 10 June 1886 until in 2016 a forgotten survey was rediscovered in Switzerland. This recently enabled researchers to reestablish the Pink and White Terrace locations which proved to lie on land; raising the possibility the sites may be investigated and any surviving sections of the terraces recovered or made open to public view.
